“King concurrent course” full name is “King concurrent course: Concurrency in Structured Cognition Java”, is a series of articles. In this series, I will take you step by step to structurally understand concurrency in Java, following the outline below, and plan to update it by August 31, 2021, with irregular weekly updates.
This series of articles is organized in different stages, and different stages represent different cognitive difficulties. The reason for using the concept of paragraph in king is not only because of the consideration of reconciliating the interestingness of the text, but also because as the cognitive difficulty increases, the difficulty of adhering to it also increases, and the latter is even more intense. Persistence, in the present is so simple and scarce.
As the saying goes, “A person who travels a hundred miles is half of a hundred.” This is true for readers, and it is even more true for me. Readers need to keep reading, and I need to keep writing. Therefore, I sincerely invite gold mining friends can pay attention to me, supervise me, put forward valuable advice, we do long termist together, together from bronze to king.
